Abstract
A display device includes a liquid crystal display panel having a display region, pixels provided in the display region and arranged in a matrix (row-column configuration) in a first direction and a second direction different from the first direction, and a pixel gradation corrector correcting a gradation value of a first pixel in accordance with gradation values of second pixels adjacent to the first pixel, the pixel gradation corrector multiplying a value indicating sensitivity with which the first pixel is influenced by the second pixels and a value indicating strength of influence that the second pixels exert on the first pixel together, and subtracting the multiplied value from an input gradation value of the first pixel to calculate an output gradation value to the first pixel.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1 . A display device comprising:
a liquid crystal display panel having a display region; pixels provided in the display region and arranged in a matrix (row-column configuration) in a first direction and a second direction different from the first direction; and a pixel gradation corrector correcting a gradation value of a first pixel in accordance with gradation values of second pixels adjacent to the first pixel, the pixel gradation corrector multiplying a value indicating sensitivity with which the first pixel is influenced by the second pixels and a value indicating strength of influence that the second pixels exert on the first pixel together, and subtracting the multiplied value from an input gradation value of the first pixel to calculate an output gradation value to the first pixel.
2 . The display device according to claim 1 , wherein the pixel gradation corrector calculates an output gradation value V1o to the first pixel using Expression (1) below when the input gradation value of the first pixel is V1i, a function indicating sensitivity with which the first pixel is influenced by the second pixels is f(V1i), number of the second pixels is N, an input gradation value of the second pixels is V2i, and a coefficient indicating strength of influence that the second pixels exert on the first pixel is Sp:

3 . The display device according to claim 2 , wherein the function f(V1i) is indicated by Expression (2) below when the input gradation value V1i of the first pixel is x, and coefficients set in advance in accordance with the sensitivity with which the first pixel is influenced by the second pixels are A, C, D, and E:
f ( V 1 i )= f ( x )= Ax 3 +Cx 2 +Dx+E (2)
4 . The display device according to claim 1 , wherein the pixels include a first pixel for displaying a first color, a second pixel for displaying a second color different from the first color, and a third pixel for displaying a third color, the third color being different from the first color and the second color.
5 . A display system comprising:
a display device including
a liquid crystal display panel having a display region, and
pixels provided in the display region and arranged in a matrix (row-column configuration) in a first direction and a second direction different from the first direction; and
an image generation device including a pixel gradation corrector correcting a gradation value of a first pixel in accordance with gradation values of second pixels adjacent to the first pixel, the pixel gradation corrector multiplying a value indicating sensitivity with which the first pixel is influenced by the second pixels and a value indicating strength of influence that the second pixels exert on the first pixel together, and subtracting the multiplied value from an input gradation value of the first pixel to calculate an output gradation value to the first pixel.
6 . The display system according to claim 5 , wherein the pixel gradation corrector calculates an output gradation value V1o to the first pixel using Expression (3) below when the input gradation value of the first pixel is V1i, a function indicating sensitivity with which the first pixel is influenced by the second pixels is f(V1i), number of the second pixels is N, an input gradation value of the second pixels is V2i, and a coefficient indicating strength of influence that the second pixels exert on the first pixel is Sp:
